ABSTRACT:
In a column of telescopically adjustable height, the two coaxial telescoping members may be adjusted axially after a control button in an axial bore of one member is depressed. A bracket, longitudinally split into two members, passes into the bore through a radial opening of the one column member and is anchored axially and radially by conforming engagement with the column member. The operating lever for the control button is pivoted between the bracket members outside the column bore so that a small angular movement of the exposed lever part causes the terminal part of the lever in the bore abuttingly to engage the control button and to depress the same.
